What is the period of the kinetic or the potential energy change if the period of position change of an object attached to a spring is 4.4 s ?

2.2 s

Explanation:

This is a simple harmonic motion problem. A simple Harmonic motion can be defined as special type of periodic oscillation where the restoring force is directly proportional to the displacement. The restoring force then acts in the direction opposite to the displacement.

All simple harmonic motion is sinusoidal.

PERIOD is the time required to complete a full cycle.

From the question, the period of position change of an object attached to a spring is 4.4 s. There are two potential energy and two kinetic energy maxima per period, therefore, we have 4.4/2 = 2.2 s.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the total distance traveled by the car is

30km + 49km = 79 km .
